What model of Seasonic? Ideally, the first post in this thread, or somewhere, should maintain a list of known, guaranteed ok PSUs that one can use with the adapters. One problem with nekochan is a lot of relevant info is incredibly fractured, and finding it often difficult due to the way the search function works. Infact, even searching for this thread brought up a different thread first.

The exact model is: Seasonic SS-500ETBut any similar modern PSU around 500Watts (combined) should work juust fine..And my Fuel is loaded (V12, 800MHz, 2x DVD Drives, 2x HDDs).Just pick a "good" brand and no need to worry about the 3.3V or 5V max load of the original Fuel's WTX PSU.I know the max wattage one is able to draw from these 3.3V and 5V lines of the modern PSUs is a bit lower than the original, but the machine doesn't consume such high amperage from these lines anyway.

I can't say cause I got it without any sort of manuals etc..Just a box with the unit.This link points to where I got it from: https://www.ekos.gr/product/ss_500et_bulk92At least all the specs are there (in Greek though )
